Professor Nick Ritchie
Professor (International Security)



Nick researches and teaches in the areas of international relations and international security at the University of York. His particular focus is on nuclear disarmament, proliferation and arms control and US and UK national security. 

After completing his PhD thesis at the University of Bradford in 2007 on the evolution of US nuclear weapons policy after the Cold War, Nick spent four years researching and teaching at Bradford’s Department of Peace Studies before joining York in 2011.

He previously worked for five years at the Oxford Research Group, an independent Non-Governmental Organisation working with policy-makers and independent experts on the challenges of global security and nuclear disarmament.



Nick’s research examines the global politics of nuclear weapons and nuclear disarmament. He has focused on the international movement since 2010 to ban nuclear weapons culminating in the Treaty on the Prohibition of Nuclear Weapons in 2017. This research agenda has centred on the valuing/devaluing and legitimation/delegitimation of nuclear weapons in national and international politics, and the power politics of nuclear hegemony and the global disarmament movement. He also researches the UK nuclear weapons programme, including the politics of the Trident replacement programme underway since 2006 encompassing options, costs, politics and Scottish independence. His work has been funded by the ESRC, Joseph Rowntree Charitable Trust and Nuclear Education Trust.
